Big expenses retirees didn’t save for - but should have
Experts and retirees identified six expenses that retirees should have saved more to cover, according to an article on TheStreet. The first was taxes. Thirteen states tax at least some Social Security income. Forty three states tax pensions. Also, the IRS will tax money withdrawn from a tax advantaged savings plan. Many seniors assume they will stop paying taxes when they retire, according to the article, but that's not true and budgets should be constructed with the tax man in mind. In addition to taxes, vacations and other fun activities are among big expenses that retirees usually fail to save for, according to TheStreet. Retirees should also consider dental expenses such as implants and dentures that may not be covered in dental insurance plans as well as hearing aids costs and other health care expenses that may not be covered in Medicare. Also, retirees should account for new car expenses every seven years until they reach 80 years old.

Rethinking a retirement nest egg
Retirees should create a budget to ensure that they don't run out of funds later in their retirement, according to Kiplinger. Common reasons for running out of money include overspending on gifts, underestimating living costs, living longer than expected and not changing investment methods after retirement. Thus, retirees should ensure that their budget reflects their projected lifestyle cost after retirement, including large purchases. Budgets should also reflect factors in inflation, assume death at age 100 or later and adopt an investment portfolio with low volatility.
